Be it known that I, CLEMENS UNVERZGT, of Terre Haute, Indiana, haveinvented certain new. and useful Improvements in Looms; and I herebydeclare vthe following to be a full, clear, and exact description Aofthe same, reference being had to the drawings which aecompanythisspecification, forming a part of the same, and l to the letters ofreference marked thereon. .In the drawings- Figure 1,-plate 1, is aperspective view of my improved loom, and v Figure 2 is avertical'sectional view, showing the batten-posts, picker-staffs,spring, and triggers.

Figure 1, plate 2, shows the notched revolving plate with its operativeshaft, and provided with separate single, double, and triple removableand adjustable arms.

Figure 2, plate 2, is a perspective view of an elongatedoval oat orfeather, which, traversing the grooves of the grooved plate, operatesthe traverse-bar and sets and releases the triggers alternately.

Figure 3, plate 2, is a perspective view of an oblong, curved,rectilinear plate, the upper surface of which is grooved, and-soarranged as, by means of the float or feather which works in the same,to -produce the backward and forward motion of the traverse-bar, towhich the float or feather .is attached, and also showing the triggersin connection with the traverse-bar.

Figure I, plate 3, shows a single arm with a hub fitted for the shaftwhich operates the heddles, and

Figure 2 is a hubwith three arms.

Figure 3, a hub with two arms, (and with additional arms shown in dottedlines,) and Figure 4 shows parallel arms upon the same hub. l

Figures and 6 are views of an adjustable hanger with pivots or pointedjournals, -upon which the arrn.

shaft is hung, .and upon which it revolves.

Figure 7, plate 3, is a view of the revolving notched plate, and thearm-shaft which it operates, and'to which it is attached. l

Figures 8 and 9 are views of a like plate provided with six and eightsides and notches respectively, and capable of being used upon a. shaftof corresponding form when a greater number of arms maybe requisitelFigure 10, plate 3, is a. side view of the adjustable hanger, showingthe screws and bolts by which it'is I .attached to the rail.

Figure 1, plate 4, is a top view of the upper section of the loom,showing the arrangement and connection of the diierent parts thereof,and the position of the triggers in dotted lines and colors, togetherwith their relative positions to the picker-staffs, both when set andwhen sprung,

Figure 2, plate 4, is a side view of the ratchet-bar in connection withthe revolving notched plate, which it serves tp rotate by its backwardand forwardmovement.

In the figures upon each plate, like figures refer to like parts.

'llo enable those'skilled in' the'art to manufacture and use my saidimprovement, I will proceed to describe the same.

In iig. 1, plate l, A A A A A represents the framing of @hand-loom ofordinary construction. B is a crank attached suitably'to abalanee-whcel, C, which, together with a similar wheel, are placed atopposite ends of a shaft, D, which is properly secured and revolves inboxes resting upon-the front ends of the side piecesof the framing A A.Thewhecls C C are each prcvidedwith crank-pins, te which are attachedthe pitmen E E', at their forward end, while the opposite ends ofthesame are properly connected to the hatten F, and situated upon theoutside of the framing ofthe loom, and by the turning of the wheels aforward and backward morir is given to the hatten by the action of thcpitmen E E. The betten is hinged, by the 'hatten-posts-I I', tothe lowersid'e pieces of the framing of the loom, upon which it is supported in asuitable manner, and is provided at each end with shuttle-boxes in whichare tension-straps, T T', .which act upon the shuttle to hold it bothdownward and backward as it is received and discharged `from either endinthe shuttle-boxesG G. -H repre. sents the reed, which is of theordinary form,l lM M are slotted orgrooved standards, attached tothe'outer Vside or inner side of the upper. side rails 'of the framingperpendicularly, and operate as a guidelack for-,fthe

rise and fall of the hcddle-frames -N N N N. These heddle-frames are ofthe ordinary form, and can be used in such numbers as may b required.The heddles are raised either separately or in such combinations as maybe required in the guide-rack, by means of revolving arms, the outerends of which are of circular form, and which are fitted upon andoperated by a shaft, a, as sce'n in iig. 1, plate 2. .This shaft, asshown, is square, and is rigidly attached to and moved by the notchedplate b, plate 2, g. 1. The arms 1' '2' 3' 4', Snc., may he constructedsingle, double, triple, or` to any required number, upon a single huborcentre, and are so ittcd'as to be put on or taken otf for the purpose ofchangingA their relative position, and thus change and control themovements of the heddles. When in position upon the shaft a, they aresecured by the key ol or in any other suitable manuel'. The shaft a hasa conical opening in each end, in which are inserted the pointedjournals d d, figs. 5 and 6, plate 3. These journals are attached to thehangers, as seen in figs. 5 and 6, plate 3; and the upper surface, a,plate 8, gs. 5 and 6, of the hanger is provided with slots or openingsfor the screws, which secure it, so that 'in case of the pointedjournals -becoming worn or loose in `their bearings, the hangers may beset up closer together, and thus secure a perfect centre.

In plat-e 2, 1, b is an equal-sided revolving plate, provided withnotches or catches at each corner, and rigidly secured upon the shaft a.The drawings show one constructed with four sides, and notches tocorrespond.; but thisplate may be formed hexagonal or octagonal, orotherwise, as the increased number-of heddles or of arms upon the shaftmay render necessary, as seen in'figs. 8 and 9, plate 3.

v Fig. 2, plate 2, represents a iloat or feather having a stem orstandard, a, a collar, I), und an oval shoe or bottom, e. 'Ihe stem orstandard a is fitted into and occupies a. hole in the central portion ofthc'traversc-.bar F', figz 3, Aplate 2, and operates said bar, as willbe hereinafter shown.

Fig. 3, plate 2, is a perspective view of a grooved plate or frameattached at either end to the erossframings of the-loom. Its uppersurface is arranged with two parallel grooves nearvthc outer edges ofthe plate, as shown at B B, fig. 3,'plate 2; connected with andconneetirfg. which are diagonal groovesl,1l' B". The traversc-bar F', inwhich the stem a ofthe iloat or feather is fixed, occupies a centralposition in the battenrail, upon its lower surface, and immediatelybeneath the shuttle-race. This bar is constructed with an offset orshoulder near each end, at which the pins e e are inserted, for thepurpose of operating' the triggers K K'. The extreme ends of thetraverse-bar F' serve to carry back alternately to the setting-point thepicker-staffs L L', where the pins e e, producing an oscillation of thetriggers K and K', alternately stop and release cach' picker-staff whichthrows the shuttle, by means of the wires or cords traversing theshuttle-boxes, an'd attached lto the shuttle-blocks therein. The shuttleis thus thrown by the backward motion of the hatten, and near the centreof its motion, leaving the hatten free play, as it comes forward, tobeat up the c loth.

It will be seen that as the ratchet-bar A' completes thefullone-.quarter revolution of the plate Z, the angle :e of its lowersurface is brought into contact with the straight side ofthe plate b,and the head m of the ratchet-bar A', entering the bracket B, plate 4,fig. 2 holds the heddles, harness, and shed fixed during the concussionof beating up the cloth by the hatten.

Attached to the head m of the ratchet-bar A' is a strap or cordrunningover a pulley on the side rail, and along the side to a peint forward ofthe battenpost, where it passes through a 'loop and is returned to thehatten-post on that side, and is secured toit. At the opposite end ofthe ratchet-bnr is secured a strap, C, which, passing around a pulley,G, iig. 1, plate 4, is attached directly to the opposite hatten-post.

In the grooved plate A, plate 2, g. 3, it will be seen that the frontends of the' transverse grooves B B are deeper than lthe correspondingends of the side grooves, while at the back ends they are equallyhigher,

which arrangement, combined with the operation of the said. grooves,insures the proper direction of the float or' feather c, whichalways-comes down on the outside grooves and returns in the diagonalgrooves.

It will be observed that the traverse-bar F','to which the lioat orfeather is attached, operates the triggers, and consequently thepicker-stads, setting one and releasing the other simultaneously, and atvone movement of the bar,' and produced by the transit of the float or'feather through one of the transverse grooves, occupying aboutone-fourth of the traverse of the hatten, and relieving thepicker-staifs from any strain during the other three-fourths of itsvibration. I

'One of the features of my invention consists in the construction of aloom without treadles, which makes it cheaper and easier of operation. lv

Another feature will be found in the facility with which any reasonablenumber and variety of combinations may be formed by the arrangement, asshown, of the revolving notched plate, the arm-shaft, and the arms.

And still another, in the traverse-bar F', operating in themannerdescribed.

The arm-shaft a, iig. 1, plate 2, is readily removed for the adjustmentaf the arms, by releasing the nuts iz', fig. 10, plate 3, by which thehanger is thus disengaged, and is as readilyreplaced in the same manner.

Havingthus fully described my said improvements, what I claim as new,and desire to secure by Letters Patent, is-

1. The combination of the grooved plate A, hatten F, feather a 6 c, andtraverse-bar F', when arranged and acting substantially'as and for thepurpose hereindescribed. l

2. The triggers K K', as set forth, in combination with the traverse-barF' and its pins e e'.

3. The combination of the traverse-bar F', feather a 6 c, and thegrooved plate A, constructed and operating as herein fully set forth.

4. The ratchet-bar A', with its head m and lower inclined surface sa, incombinationwith the inclined bracket B and notched revolving plate-wheelb, as and for the purposes set forth. Y

5. The combination of the shaft D, wheels C C', pit'men E E', batteriF,`traverse-bar F', feather a I) c, and grooved plate A, all asconstructed and arranged, as is herein substantially set forth.

` 6. The combination of the siidingratohet-br A, constructed asdescribed, with the strap C, cord D, or their equivalents, when operatedbythe botten F,'for the purposes set forth. A

7. The arrangement and combination of devices herein set'forth, bj whichthe picker-stais are set and sprung alternately.simultaneously by thebackward motion of the hatten.

8. The combination of the picker-staffs L L, triggers K K', andtraverse-bar F', when arranged and constructe as is herein set forth. 'ACLEMENS UNVERZAGT.
